In summary, the conversation is about solving a problem involving a cart on wheels with a motor-driven propeller. The problem includes a mass of 250 g, a force of .3 N, an incline of 30 degrees, and an acceleration of 3.5 m/s^2. The person also asks about the force of friction and the coefficient of friction. The response advises them to draw a free body diagram and use equations of motion instead of looking for shortcuts.

can anyone show exactly how to solve this problem with equations and all?


a cart on wheels with a mass of 250 g has a motor driven propeller with a force P of .3 N, and it moved down an incline of 30 degrees with an acceleration of 3.5 m/s^2.

What is the force of friction ?

determine coefficent of friction?


Thanks!

No, because it wouldn't help you. From your other post, I know your knowledge is very sketchy, and if you continue to look for shortcuts, you will come short in the exam.

FAQ: Incline HW Problem: Solving with Equations and Finding Coefficient of Friction

What is the concept of an inclined plane?

The concept of an inclined plane is a simple machine that is a flat surface that is tilted at an angle. It reduces the amount of force needed to move an object up or down the plane by increasing the distance over which the force is applied.

How do I calculate the mechanical advantage of an inclined plane?

The mechanical advantage of an inclined plane is calculated by dividing the length of the ramp by the height of the ramp. This ratio represents the amount of force needed to lift an object on an inclined plane compared to the amount of force needed to lift the same object vertically.

What is the relationship between the angle of the inclined plane and its mechanical advantage?

The angle of the inclined plane and its mechanical advantage have an inverse relationship. As the angle of the plane increases, the mechanical advantage decreases. This means that a steeper inclined plane requires more force to lift an object compared to a shallower inclined plane.

How does friction affect the efficiency of an inclined plane?

Friction can decrease the efficiency of an inclined plane by making it more difficult to move an object up or down the plane. This is because friction creates a force that acts in the opposite direction of the intended motion and must be overcome by a greater applied force.

How can I use an inclined plane to make work easier?

An inclined plane can make work easier by reducing the amount of force needed to move an object up or down a ramp. This is because the force is spread out over a longer distance, making it easier to lift the object. Additionally, the mechanical advantage of the inclined plane can also make work easier by reducing the force needed to lift an object compared to lifting it vertically.
